In the clinical management of voice clients, it is important to measure accurate pitch ranges in order to determine if a client has a normal range or is speaking at an optimum pitch. It is not clear from the literature which vowel should be used in determining these pitch ranges. The purpose of this investigation was to determine the phonational frequency ranges in adults with no vocal training when phonating the cardinal vowels of /i/, /u/, and /a/. The investigation sought to answer the following question: Does the phonational frequency range in vocally untrained adults vary significantly when phonating the cardinal vowels of /i/, /u/, and /a/?
